Discovery continues to dominant litigation brought by Jasper County resident Tommy Carrell Jr., who sued Motiva Enterprises for alleged injuries he received in an explosion that occurred in July 2011 at the Port Arthur refinery.

As previously reported, the suit was filed Feb. 5 in Jefferson County District Court.

Court records show the latest filing in the suit was a certificate of discovery filed Aug. 27.

The document shows Motiva served Carrell with its second request for production.

According to the lawsuit, on July 31, 2011, Carrell was working at the Motiva facility when an explosion occurred, causing him to suffer bodily injuries.

The suit accuses Motiva of negligence but declines to list any specific act of negligence allegedly committed by the company.

Carrell is suing for his alleged past and future medical expenses, mental anguish, pain, impairment and lost wages.
